I replaced the motor for the z4 top pump, but the shaft in the square pump housing won't spin at all. I think I got all the pins (the three silver pins in the bushing, and the spring pin that connects to the motor) aligned correctly, but the motor just spins and no fluid moves. Is there a way to unlock the shaft? I tried playing with the release cable too, and that didn't seem to help. I'm guessing I need to get a new pump now, but thought I'd check here first. Thanks.
